Thus, accurate measurements of the distribution and variability of dust are required. Observations from the Mars Global Surveyor\/Thermal Emission Spectrometer Mars Mars Reconnaissance Orbiter\/Mars Climate Sounder and Mars Express\/Fourier Transform Spectrometer and the Curiosity Rover have limited capability to measure dust. We show that spacecraft occultation of the Martian atmosphere at far-infrared frequencies between 1 and 10 THz can provide the needed global and temporal data on atmospheric dust by providing co-located measurements of temperature and dust opacity from the top of the atmosphere all the way down to the surface. In addition, spacecraft occultation by a small-satellite constellation could provide global measurements of the development of dust storms.<\/jats:p>","DOI":"10.3390\/rs15184574","type":"journal-article","created":{"date-parts":[[2023,9,17]],"date-time":"2023-09-17T23:32:27Z","timestamp":1694993547000},"page":"4574","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Probing Dust and Water in Martian Atmosphere with Far-Infrared Frequency Spacecraft Occultation"],"prefix":"10.3390","volume":"15","author":[{"given":"Ananyo","family":"Bhattacharya","sequence":"first","affiliation":[{"name":"Department of Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}]},{"given":"Cheng","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}]},{"given":"Nilton O.","family":"Renno","sequence":"additional","affiliation":[{"name":"Department of Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}]},{"given":"Sushil K.","family":"Atreya","sequence":"additional","affiliation":[{"name":"Department of Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3334-5227","authenticated-orcid":false,"given":"David","family":"Sweeney","sequence":"additional","affiliation":[{"name":"Department of Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"NASA Jet Propulsion Laboratory, Pasadena, CA 91109, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"980","DOI":"10.1002\/jgre.20084","article-title":"The impact of a realistic vertical dust distribution on the simulation of the Martian General Circulation","volume":"118","author":"Guzewich","year":"2013","journal-title":"J.
